Top Traders Unplugged | Systematic Investor Series Episode 398: "Navigating a VUCA World"
Host: Niels Kaastrup-Larsen
Guest: Mark Rzepczynski
Date: May 2, 2026
Episode Overview
This episode explores how systematic and quantitative investors can navigate highly uncertain, complex, and volatile markets—a so-called "VUCA" world (Volatility, Uncertainty, Complexity, Ambiguity). Niels and Mark reflect on recent market events, the response of trend-following strategies, the psychology of reacting to shocks, the challenge of replication, and the evolving role of artificial intelligence (AI) in finance. This discussion sheds light on portfolio resilience, investor sophistication, and the interplay between information, narratives, and price signals.
Key Discussion Points & Insights
1. Living in a VUCA World
[01:14] Mark: "We're living in a VUCA world now... uncharted territories. And the question is how do you navigate that, especially if you might be a quant investor?"
- The environment is characterized by volatility, uncertainty, complexity, and ambiguity.
- Investors, particularly quants/systematic strategies, are challenged to adapt and survive.
2. Uncharted Territory: Recent Market Events
[03:26] Niels:
- Record-breaking marathon times and even robots outperforming humans are analogies of breaking boundaries.
- Massive $6bn hedge fund redemption reflects changing investor sophistication.
- Jerome Powell stepping down as Fed Chair but remaining on the board—an unusual precedent. Market implications hinge on successor’s policy (Warsh) and attitude toward quantitative easing.
- UAE leaving OPEC: A major energy development raising questions about increased volatility in oil markets.
[07:16] Mark:
- UAE’s pipeline capacity (1.5–2 million barrels/day) and intention to maximize supply amidst crisis.
3. Trend Following Performance Amid Turbulence
[07:53] Niels:
- Despite global shocks, April was strong for trend following/CTAs—possibly even all-time highs on indices like SocGen Trend.
- Performance is broad-based across sectors, not just “crisis alpha” (making money when everything else falters).
[10:16] Mark:
- The “Goldilocks” condition: Trend following thrives when crises are sustained, allowing trends to develop and managers to adapt.
- Quick reversals (e.g., March 2020 pandemic crash) are tougher for CTAs.
"The longer the crisis, the better you'll be for a trend follower." [10:16]
[11:36] Niels:
- Fixed income has been a pain point, but short exposure is gaining traction as rates rise.
- Replication of CTA exposures by investment banks (e.g., predictions on large equity buys/sells) often falls short of accuracy.
4. The Challenge of Replication & the Role of AI
[14:06] Mark:
- Replicating trend followers is an old game, now turbocharged by AI.
- Mimicking Finance: Recent studies show AI agents can replicate about 70% of average manager behavior, but struggle with the "dynamic" edge of top managers.
"You can mimic the average, but you'll underperform the best managers." [15:06]
[16:58] Mark:
- Replication struggles with non-linear strategies—especially breakout/trend triggers, not just simple moving averages.
- Non-linear rules are hard to reverse-engineer or copy via indices or AI agents.
[18:43] Niels:
- Many replicators miss the essence and performance of the best managers, especially in managing drawdowns and capturing dynamic risk management.
[21:22] Mark:
- High correlation in returns doesn’t mean stable or meaningful replication, especially if beta is negative.
5. Performance Data Snapshot (April 2026)
[22:42] Niels:
- CTAs and trend-following indices all report strong year-to-date and April numbers:
- BTOP 50: April +1.84%, YTD +9.46%
- SocGen Trend: April +2.45%, YTD +9.71%
- Short-Term Traders: April +0.56%, YTD +5%
- Equities also performed well (e.g., MSCI World April +8.35%, YTD +4.59%)
6. Geopolitical Risk and Market Response
[24:44] Mark:
- Prolonged Middle East crisis = extended, persistent trends across commodities and equities.
- Supply shocks are harder for economies to manage than demand shocks:
- Demand: Central banks lower rates, provide stimulus.
- Supply: Limited tools, risk of inflation if policy overreacts.
- Spillover to markets like fertilizer, propane/butane, with real economic consequences.
[27:50] Notable Quote:
"With a supply shock, what do you do about that? It becomes a little bit more difficult to deal with because do you accommodate a supply shock which would then add to inflation?" [24:44]
- Parallels to the 1970s; possible long-running market trends.
7. Surprise and Market (Non-)Reactions
[28:54] Mark:
- Reference to “World War I problem”—markets often do not price in risks until after shocks occur.
- Despite energy shock, volatility (VIX) remains low, equity markets resilient.
"It's like the dog that didn't bark." [27:50]
- Ambiguity and “being numb” lead to slow investor reaction, longer market trends.
- Greater uncertainty → slower decisions → longer, more pronounced trends—good for trend following.
8. Information Flow, Psychology & Model Horizons
[33:15] Niels:
- Even with instant info (post-internet), longer-term trend models outperform short-term strategies.
- Processing, not receiving, information is the bottleneck.
"Our ability to gain information is better than ever... but our ability to process that information may not have improved." [34:55 - Mark]
9. How Supply Shocks Favor Trend Following
[36:46] Mark:
- With supply shocks, government responses are ambiguous or delayed, so price discovery relies on markets—allowing trends to persist.
- In contrast, government interventions (e.g., March 2020 monetary/fiscal response) can reverse or disrupt trends, but sometimes open new opportunities.
[39:25] Mark:
- Pandemic response: Monetary and fiscal stimulus to counter a supply shock caused inflation, benefiting trend followers with strong later trends.
10. Hedge Fund Strategies: Sensitivity to Risk & Regimes
[40:48] Mark:
- New research: Most hedge fund strategies underperform in high-volatility regimes, despite claims of “crisis resistance.”
- Only trend following/managed futures and, to some extent, global macro are truly resilient to shifts in volatility and risk shocks.
"If you're really worried about risk in your portfolio... managed futures will be a better choice than many of these other strategies that may generate alpha, but that alpha is actually dissipated once you take into account how the risk regime you have." [44:01]
11. The Power of Narrative vs. Numbers
[51:04] Mark:
- Daniel Kahneman: “No one ever made a decision because of a number. They need a story.”
- Investors gravitate to managers with stories and context, even if systematic (trend) strategies just follow price.
"The confidence that individuals have in their beliefs depends mostly on the quality of the story they can tell about what they see, even if they see little." — Kahneman [51:13]
- The challenge: How to add “context” or narrative to quant models, and whether sentiment analysis (via NLP/LLMs) can be systematically useful.
12. AI, Multi-Agent Models, and the Future of Quantitative Research
[56:45] Mark:
- AI models can combine agents (e.g., price-based, fundamental, sentiment) for potential higher Sharpe ratios.
- Many trend managers now blend strategies, making "pure trend" funds rarer.
- There is an ongoing debate: should investors bundle strategies (multi-strat) or allocate to pure, orthogonal strategies themselves?
"When you think about a manager that uses a number of different strategies, he's acting like a multi-agent LLM." [58:48]
13. Bundling vs. Pure Strategies
[60:01] Mark:
- Classic investor dilemma: buy bundled strategies (easier, more packaged) or assemble portfolios of “pure” strategies?
- Wall Street excels at bundling (sometimes with unintended side effects, e.g., CDOs in the GFC).
"There's good bundling and bad bundling and sometimes we may not know what is good or bad bundling until after the fact." [62:58, Mark]
14. Research Frontiers: Deep Momentum & Momentum Crashes
[63:20] Mark:
- Emerging research on momentum: lots of noise among past winners, some crash sharply (“momentum crashes”), challenging simple narratives.
- More investigation needed into detailed return behavior; to be discussed in future episodes.
Notable Quotes & Moments
- VUCA world: "We're living in uncharted territories. And the question is how do you navigate that?" [01:14, Mark]
- On hedge fund replication: "You can mimic the average, but you're generally going to underperform. But you can't mimic the best managers." [15:06, Mark]
- On investor expectations: "Their sophistication has increased, they demand more from the managers that they invest with." [03:59, Mark]
- On narratives: "No one ever made a decision because of a number. They need a story." [51:13, Mark quoting Kahneman]
- On information overload: "Our ability to gain information is better than ever... but our ability to process that information may not have improved." [34:55, Mark]
- On pure vs. bundled strategies: "Should you buy it bundled or should you buy the component parts?" [60:01, Mark]
